- To-all whom it'may concern:

Be it known: that we, BENJAMIN F. CoLBY and Gnoncn L. Swasnr, both citizens of the United States, and residing at Boston, in the county of Suffolk and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a full, clear,-and exact specification.

The object of this invention is the construction of improved means for preventing bottles from being filled a second time, while still permitting their easy emptying.

Referring to the drawings forming part of this specification, Figure 1 is a side sectional elevation of the upper part of a bottle, showing our improvements connected therewith. Fig. 2 is a central vertical section of the stopper device alone. Fig. 3 is a horizontal section 01": the same. Fig. 4 is a perspective view of the cylindrical portion of said device. Fig. 5 is a perspective view of the valve-stem guide and valve protector. Fig. 6 is a side View of the latter. Fig. 7 is a side view of the valve alone.

The bottle 1 is of well known construction, with the exception that within its neck at a point about one and three-fourths of an inch from the mouth is formed a shoulder 2, and the interior of the neck 3 above the shoulder is made cylindrical and exact to size.

The stopper device comprises three distinct and originally separate parts; a cylindrical member at, a valve-stem guide and valve protector 5, and a valve 6. The cylinder t is formed with a floor 7 having a conical seat 9 (Fig. 2) and radially through the cylinder are three holes 10 disposed equidistantly about the same, as shown in Figs. 4: and 3.

Themember 5 consists of a thimble 11 having three spaced ribs 12 extending vertically thereon, the outer edges of the ribs fitting snugly within the cylinder 4. At the lower edge of the thimble 11 is a flange 13 equal in diameter to the interior of the cylinder 4. V

The valve 6 fits the seat 9, and has a stem 14 slidable within the thimble 11. The valve having been introduced within the cylinder, the member 11 is pressed down in the latter until its flange 13 is positioned inline with the centers of the holes 10, as shown in Fig. 2. The cylinder is then coated externally with a suitable cement and introduced withtion of the bottle neck in the usual manner.

lVhen it is desired to empty the bottle, either entirely or a part at a time, the stopple is removed and the bottle tipped up. Aided both by gravity and the pressure of the bottles contents, the valve 6 moves away from the seat 9 and permits the liquid to pass through the seat opening. From this opening the liquid passes in and out of the holes 10 about the edges of the flange 13, and thence out through the remainder of the neck and the mouth.

It should be noted that it is the thickness of wall of the cylinder 4: which provides the space for the liquids flow, said thickness multiplied by the diameter of a hole 10 giving a passage fully equal to the seat-openmg.

We have discovered it requires three openings for the free flow of the bottles contents; that less or more will not serve the purpose of providing admission for the air coincident with the outflow of the liquid. With the three openings 10 and the separating ribs 12 between them, it is impossible to present the bottle in any way to interfere with the admission of air to take the place of the liquid outflow. hen the bottle is turned back, with its mouth uppermost, gravitation causes the valve to drop down upon the seat 9,its stem sliding freely in the thimble 11,and so insures against any refilling of the bottle.

As is evident upon inspection of Fig. 2, the flange 13 prevents the introduction of a wire or other device in vain attempt at reaching the valve for holding it up in order to refill the bottle. In no other way, also, so far as we have been able to determine, is it possible to so manipulate this bottle as to enable it to be filled a second time.

hat we claim is:

1. Ihe combination with a bottle, of a hollow cylinder having its exterior contacting with the interior of the bottle-neck, said cylinder having a plurality of holes radially through the same with their centers in the same horizontal plane, said cylinder being formed with a floor having an opening formed with a valve seat, a valve for closing said opening, a thin horizontal disk located within the cylinder at the level of the centers of said holes, the disk being formed with vertical ribs equal in number to said holes,-each rib coming between tWo of said holes and contacting With the interior of said cylinder.

2. The combination With a bottle having a neck, of a hollow cylinder fastened Within said neck With its peripheral surface cemented to the inner surface of the neck, the cylinder having three equal holes radially through it, the centers of the holes being in the same transverse plane, the cylinder having a floor formed with a valve opening, a thln dlsk having three I'lbS and a valve-stein guide, the periphery of the disk and the outer edges of the ribs fitting tightly Within the cylinder, the disk being located in the same transverse plane With the centers of the three holes, and each rib being between tWo of the holes, and a valve having a valve-stem, the valve-stem being slidable in the valve-stem guide, and the valve be ing in the shape of a frustum of a cone and,
